It worked in FT, when you needed exact builds (players were getting same example builds from the clan site, or did them for yourself, but still they were same) it was balanced, and one more thing,people WEREN'T using drugs on some popular rulesets (2kh1, 2kh3, 1k, 5k) but only on 10k, and 150k, so your statement is failure.
Here people are mini-maxing builds, to get more than enough skill points, and enough st to use the weapon without penalty (or at least doing +20% more skill but -1 str and still it works).
It could work but in other way : change weapons reqs, like avenger for 8 str (like its in Ft, fair) bazooka and flamer for 6 st, lsw, m60 for 7 st.
This is just a proposition, if you don't like, write why, please.
